Configuring Your Ringtone
In order to set a ringtone on your Windows Phone, the file must have the following properties:
- It must be in MP3 or WMA format.
- It must have playback duration of less than 40 seconds.
- The file should be under 1 MB.
- Your intended ringtone file must not be protected with digital rights management (DRM).
Most of these specifications exclude standard MP3 and WMA files, which of course means that you will have to create your ringtone using a cropping tool.
There are several available that are free to download. One popular option is Audacity, the open source audio editor (you might also use the Windows XP version of Windows Movie Maker, which has some audio editing capabilities) and this is available from http://audacity.sourceforge.net/download/beta_windows
Once you have downloaded the latest version (a modest 14.8 MB) run the installer to add it to Windows and follow the on-screen instructions. Upon installation, Audacity should run, and you will be able to begin editing your intended ringtone.
Use File > Open to browse for the original MP3 file that you want to use -- when open, you will see the audio of the file represented in blue, and a timeline across the top of the window. Remember that the maximum duration of your ringtone is 40 seconds, so if your file is longer than this you will need to use the trim tool, available via the Edit menu or by pressing CTRL+T.
To use trim, left click and drag the cursor across the selection of the music that you want to keep, and then trim the file down. You can click play to get an idea of how it will sound, and if you’re unhappy simply go to Edit > Undo or tap CTRL+Z to reverse the trim and try again.
